CXA2503 Overview

Decoder/Driver/Timing Generator for Color LCD Panels

CXA2503AR
Decoder/Driver/Timing Generator for Color LCD Panels
Description
The CXA2503AR is an IC designed exclusively to
drive color LCD panels LCX005BK/BKB and
LCX009AK/AKB.
This IC greatly reduces the number of circuits and
parts required to drive LCD panels by incorporating
RGB decoder functions for video signals, driver
functions, and a timing generator for driving panels
onto a single chip.
This chip has a built-in serial interface circuit and
electronic attenuators which allow various mode
settings and adjustments to be performed through
direct control from an external microcomputer, etc.
